please take a look.

The spec doesn't explicitly cover this case,

 https://w3c.github.io/DOM-Parsing/#dom-domparser-parsefromstring

but API uses from "detached" context aren't always.

The behavior provided for this corner case felt the most sensible to me; i.e., I
don't see the real value gained by throwing an exception.

Gecko has the same non-throwing behavior.
